Fluid Level And Refill - Peterbilt 348 2017 Operator's Manual

•
Draglink tube clamp: Check for
looseness or interference.
•
Ball joints and steering U-joints:
Check for looseness.
•
Steering wheel for excessive
free-play. Check the simplest
probable causes first:
a. unequal tire pressures
b. loose cap nuts
c. bent crosstube
d. lack of lubrication
•
If these checks do not reveal the
problem, or if you correct them
and still have a steering problem,
take your truck to an authorized
dealer for evaluation.

Fluid Level and Refill

Have the power steering fluid and
filters changed at an authorized dealer.
CAUTION
When adding fluid, be sure to use
fluid of the same type. While many
fluids have the same description and
intended purpose, they should not
be mixed due to incompatible ad-
ditives. Mixing incompatible fluids
may lead to equipment damage.
•
Check and completely change the
fluid level according to Preventive
Maintenance Schedule on page
5-12. Use the following procedure:
NOTE
Before removing reservoir cover,
wipe outside of cover so that no dirt
can fall into the reservoir.

STEERING SYSTEM
•
Maximum/Minimum level is
indicated on the reservoir. These
same levels are also indicated by
two lines on the dipstick in the
reservoir.
•
There are two ways to check
whether the power steering fluid
is at its proper level. Both checks
are with the engine NOT running.
1. If you check the fluid with the
engine and steering system
COLD, the fluid level should be
at/or above the Minimum indicator
level and should generally not
exceed the middle point between
Maximum and Minimum level
indicators.
2. If you check the fluid with the
engine and steering system
WARM, the fluid should NOT
exceed the Maximum level
indicator and should generally
not drop below the middle point
